Atkins Associate Administrator Office of Spectrum Management WAC/050 (10.04.18) UNITED STATES OF AMERICA DRAFT PROPOSAL FOR WRC-19 Agenda Item 1.1: to consider an allocation of the frequency band 50-54 MHz to the amateur service in Region 1, in accordance with Resolution 658 (WRC-15) Background The WRC-19 agenda item 1.1 proposes studies to explore the possibility of global harmonization of the 50-54 MHz frequency band for the amateur service. The ITU currently allocates the 50 – 54 MHz frequency band to the amateur service on a primary basis in Regions 2 and 3. In Region 1, the band is currently allocated to only the broadcasting service on a primary basis. However, No. 5.169 of the Radio Regulations provides for an alternate allocation to the amateur service on a primary basis to a number of countries in Region 1, and No. 5.165 provides an alternate fixed and mobile, except aeronautical mobile, allocation on a primary basis to a number of countries in Region 1. WRC-15 decided to study the sharing between the amateur service and incumbent services in Region 1 towards an allocation that would facilitate further worldwide harmonization and international operability. The frequency range 30 - 80 MHz marks the transition area between ionospheric and non- ionospheric propagation modes, which makes it particularly interesting for experimentation and study within the amateur service. Radio amateurs utilize allocations to the amateur service to engage in scientific and technical investigation and experimentation, provide communication in the wake of natural disasters, provide non-commercial public service communications, and conduct other activities to advance technical education, develop radio operating technique, and enhance international goodwill. These characteristics and the use of the band fulfill the objective of the service as defined in article 1.56 of the Radio Regulations and engage the practitioners in scientific and technical investigations, as well as helping to develop radio-operating techniques also useful for emergency communications. WAC/050 (10.04.18) Proposal: NOC USA/1.1/1 47-75.2 MHz Allocation to services Region 2 50-54 AMATEUR 5.162A 5.167 5.167A 5.168 5.170 Reasons: No change is proposed for Region 2. Any changes made to the Radio Regulations under WRC-19 agenda item 1.1 must not impact the existing allocation to the amateur service in 50-54 MHz in Region 2, nor subject Region 2 to any changed procedural or regulatory provisions. __________ WAC/050 (10.04.18) UNITED STATES OF AMERICA DRAFT PROPOSAL FOR WRC-19 Agenda Item 1.3: to consider possible upgrading of the secondary allocation to the meteorological-satellite service (space-to-Earth) to primary status and a possible primary allocation to the Earth exploration-satellite service (space-to-Earth) in the frequency band 460-470 MHz, in accordance with Resolution 766 (WRC-15) BACKGROUND: The 460-470 MHz frequency band is allocated on a primary basis to the fixed and mobile services. The meteorological-satellite service currently has a secondary allocation in this band. Under No. 5.289, “Earth exploration-satellite service applications, other than the meteorological-satellite service, may also be used in the bands 460-470 MHz for space-to-Earth transmissions subject to not causing harmful interference to stations operating in accordance with the Table”. Within this frequency band the Argos Data Collection System (ADCS) monitors more than 21,000 active Argos platforms collecting data for over 2,000 distinct projects in 100+ countries. The administration of the Argos program is under a joint agreement between the National Oceanic and Atmospheric Administration (NOAA) within the United States and the French Space Agency, Centre National d’Etudes Spatiales (CNES). Additional partners include the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT), and the Indian Space Research Organization (ISRO). Critical applications of the ADCS include atmospheric and ocean monitoring/research, tropical cyclone forecasting, fishery management, oil spill tracking, fishing vessel tracking, search and rescue modeling (at sea), anti-piracy alerting, import/export and hazardous materials tracking, endangered species studies, migration mapping, and wildlife tracking and management. The meteorological-satellite (space-to-Earth) service operates on a secondary basis relative to the fixed and mobile services and thus it must not interfere with these services. To protect the fixed and land mobile services within the United States, a power flux density (pfd) of -152 dB(W/(m2∙4kHz)) has been imposed on the meteorological-satellite (space-to-Earth) service. In accordance with Resolution 766 (WRC-15), the ITU-R is conducting sharing studies to ensure the protection of incumbent services and to develop a pfd limit that will protect incumbent services globally from potential interference in the frequency band 460 – 470 MHz. Studies have demonstrated that sharing is possible between meteorological-satellite (space-to-Earth)/earth-exploration-satellite (space-to-Earth) services and the incumbent services in the 460 – 470 MHz frequency band if the new pfd limits are applied. Based on the results of sharing studies, WAC/050 (10.04.18) this proposal supports an allocation upgrade from secondary to a primary for the meteorological-satellite service (space-to-Earth) and a new primary allocation to the earth-exploration-satellite (space-to-Earth) service in the frequency band 460 – 470 MHz band. This proposal applies the new pfd limits to the meteorological-satellite and earth exploration-satellite services in order to protect the incumbent services globally. Proposal: ARTICLE 5 Frequency allocations Section IV – Table of Frequency Allocations (See No. 2.1) MOD USA/AI 1.3/1 460-470 MHz Allocation to services Region 1 Region 2 Region 3 460-470 FIXED MOBILE 5.286AA METEOROLOGICAL-SATELLITE (space-to-Earth) EARTH-EXPLORATION-SATELLITE (space-to-Earth) 5.287 5.288 MOD 5.289 5.290 ADD 5.A103 ADD 5.B103 ADD 5.C103 WAC/050 (10.04.18) Reason: The upgrade from the secondary MetSat and EESS allocations to primary will bring regulatory stability and certainty to decades of investments for the space agencies involved in Satellite Data Collection Programs. Also, this upgraded allocation will ease coordination effort for Administrations. MOD USA/AI 1.3/2 5.289 Earth exploration-satellite service applications, other than the meteorological-satellite service, may also be used in the band 1 690- 1 710 MHz for space-to-Earth transmissions subject to not causing harmful interference to stations operating in accordance with the Table of Frequency Allocations. ADD USA/AI 1.3/4 5.A103 In the frequency band 460-470 MHz, earth stations in the meteorological-satellite (space-to-Earth) and earth-exploration-satellite (space-to- Earth) services shall not claim protection from, stations of the fixed and mobile services. Reasons: The incumbent fixed and mobile allocations maintain a higher regulatory status over the primary meteorological-satellite (space-to-Earth) and earth exploration-satellite (space-to-Earth) services by not being required to protect the metrological-satellite and earth-exploration satellite services. ADD USA/AI 1.3/5 5.B103 In the frequency band 460-470 MHz, in order to protect systems of the fixed and mobile services, stations in the meteorological- satellite (space-to-Earth) and earth exploration-satellite (space-to-Earth) services shall comply with the power flux density limits listed below. 1) For the non-GSO spacecraft is: ‒ 157 0° ≤ < 5° 푝푓푑 (dB(W /(푚2 4kHz))) = ‒ 157 + 0.5(α ‒ 5) 5° ≤ < 15° { ‒ 152 15° ≤ ≤ 90° 2) For the GSO spacecraft is: 푝푓푑 (푑퐵(푊/(푚2 4푘퐻푧))) =‒ 156 + 3/90 × 훼 0° < < 90° where is the angle of arrival above the horizontal plane, in degrees. (WRC-19) WAC/050 (10.04.18) Reasons: The meteorological-satellite (space-to-Earth) and earth exploration-satellite (space-to-Earth) services shall protect the incumbent fixed and mobile services by restricting their operations according to these pfd limits. ADD USA/AI 1.3/6 5.C103 In the frequency band 460-470 MHz, stations in the earth exploration-satellite service (space-to-Earth) shall not cause harmful interference to stations in the meteorological-satellite service (space-to-Earth).
